How to Calculate Liquidation Price on Bybit? (Margin Calculator)

Understanding Liquidation Price Fundamentals

1. Liquidation price represents the market price at which a leveraged position on Bybit is automatically closed to prevent further losses.

2. It is determined by the initial margin, maintenance margin requirement, entry price, leverage level, and position size.

3. For long positions, liquidation occurs when the market price drops to or below the calculated liquidation price.

4. For short positions, liquidation triggers when the market price rises to or above the liquidation price.

5. Bybit uses a tiered maintenance margin system for larger positions, meaning the required margin percentage increases as position size grows.

Key Variables in the Bybit Liquidation Formula

1. Initial Margin equals position value divided by selected leverage — it reflects the user’s own capital allocated to open the trade.

2. Maintenance Margin is the minimum equity required to keep the position open, expressed as a percentage of position value and adjusted per tier.

3. Position value is derived from the number of contracts multiplied by the contract multiplier and mark price.

4. Funding rate and insurance fund contributions do not directly impact liquidation price calculation but affect realized equity over time.

5. Bybit calculates using mark price rather than last traded price to mitigate manipulation risk during volatile conditions.

Difference Between Isolated and Cross Margin Modes

1. In isolated margin mode, each position has its own dedicated margin balance; liquidation depends solely on that position’s equity and maintenance threshold.

2. In cross margin mode, all available wallet balance is shared across open positions; liquidation occurs when total account equity falls below aggregate maintenance margin requirements.

3. Isolated margin allows precise control over risk exposure per trade and enables setting custom liquidation prices via margin adjustment.

4. Cross margin increases capital efficiency but introduces interdependence — a loss in one position can jeopardize others.

5. Bybit displays separate liquidation price indicators for both modes on the trading interface, updated in real time with market movement.

Manual Calculation Example for a Long Position

1. Assume BTCUSDT perpetual contract, entry price $60,000, position size 10 contracts, contract multiplier 1 BTC, leverage 10x.

2. Initial margin = (10 × 1 × 60,000) / 10 = $60,000.

3. Maintenance margin rate for this tier is 0.5%, so maintenance margin = 10 × 1 × 60,000 × 0.005 = $3,000.

4. Liquidation price ≈ entry price × (1 − initial margin / position value + maintenance margin / position value) → simplified to $60,000 × (1 − 1/10 + 0.005) = $54,300.

5. Bybit’s actual formula accounts for fees and uses mark price-based adjustments, resulting in slight deviations from manual estimates.

Frequently Asked Questions

Q: Does Bybit charge a fee upon liquidation?A: Yes. A liquidation fee equal to 0.01% of position value is deducted from the remaining equity before closure.

Q: Can I adjust my liquidation price after opening a position?A: In isolated margin mode, adding or reducing margin manually changes the liquidation price dynamically — increasing margin pushes it further from entry for longs.

Q: Why does my liquidation price change even when the market is flat?A: Mark price updates continuously based on index price and funding data; maintenance margin tiers may shift with position size fluctuations due to PnL accrual.

Q: What happens if my position is liquidated but the market reverses immediately?A: Liquidation is irreversible. Once triggered, the order executes at the best available price within the liquidation engine, regardless of subsequent price action.
